Root Cause
Please check if the address of VAM4C is 32 or not.
As stated in our manual, address 32 is reserved for Master Unit, and only one device can be set to Master mode in one Arc system, if two masters exist in same Arc system, it will cause some errors in system.

Solution
Set the address of VAM4C to another address except 32 and install the system again.
